Water Online Highlights

  1. Next-Level Flow And Level Instrumentation
    10/16/2019

    Trending issues require innovative solutions, and KROHNE is here — in the marketplace, at WEFTEC, and on video — to help water professionals overcome their toughest challenges. Tune in below for Richard Lowrie, Water and Wastewater Industry Manager for KROHNE, as he presents two cases in point: the TIDALFLEX flow meter and the OPTIWAVE 1400 radar level transmitter. The former performs accurate measurement in partially filled pipes — down to 10 percent — which is especially useful for stormwater/combined sewer overflow (CSO) applications, while the latter is a new offering that provides continuous, non-contact level measurement in tanks, pumping stations, and open channels. Learn the unique properties and benefits of each, and how they can update and improve your operations.

  2. Transitioning To Turbo Blowers
    10/16/2019

    In 2019, Kaeser Compressors assumed control of the venerable line of PillAerator turbo blowers, strengthening its ability to serve the wastewater industry — or wherever else atmospheric process air is needed on a constant pressure level. Watch this video to understand what inspired the decision, as Manual Dias, Business Development Manager at Kaeser, covers the advantages that turbo blowers offer versus other types of blowers. Al Moreno, Kaesar's District Manager, then highlights the company's screw blower technology, followed by Global Product Manager Peter Werhahn, who provides the business case for investing in turbo blowers.

  3. Improved Control Of Pre-Oxidation Variables In Drinking Water Treatment
    10/16/2019

    Using sodium permanganate or potassium permanganate can provide adequate pre-oxidation to remove organics and/or dissolved metals, such as manganese and iron, from water.  However, this typically presents operational challenges in calculating and maintaining the correct feed rate of permanganate. For a relatively small investment, instrumentation is available to help water quality managers reliably monitor and control the process.

  4. L.A. County Cities Win Legal Fight Against Stormwater Rules
    10/16/2019

    The most populous county in the U.S. is in the middle of a conflict around watershed management. And those opposed to stricter regulations have just received a boost in court.

  5. Pros And Cons Of Tertiary RO Wastewater Recycling For Municipal And Industrial Organizations
    10/15/2019

    Tertiary RO waste water recycling has become a suitable solution to augment water supplies to combat water scarcity across the world. RO desalination in tertiary wastewater processes has proven to provide a cost efficient way to reuse water for both municipalities and industrial organizations.

  6. Dangerous Waters In A Changing World
    10/15/2019

    Americans and Canadians got a peek into the future when the City of Toledo shut its drinking water taps in 2014, issuing a do-not-drink order on the municipal water supplies serving 500,000 people. Levels of microcystin, a potent liver toxin produced by blue-green algae, were more than double the World Health Organization's safe limit. More than 700 square miles of the Lake Erie surface was covered by a harmful algal bloom (HAB), and drinking water plants couldn't remove the algal cells and the toxins they produced.

  7. How The Chloramination Curve Should Be Shaping Your Disinfection Process
    10/15/2019

    The rate at which chlorine residual occurs when ammonia is added to or present in the water during chloramination follows a different course than straight chlorination. Plotting that course is known as the chloramination curve, or breakpoint chlorination curve. While the concept is complex, understanding the curve and its implications can go a long way toward preventing quality problems in the water distribution system.

  8. Overcoming Challenges To An Optimal Chlorine-Ammonia Balance
    10/15/2019

    One of the biggest headaches for water treatment plant operators is maintaining the proper balance of chlorine and ammonia that produces monochloramine. The approach to monitoring — including the choice of technology, deciding what to monitor, and setting parameters — is critical to understanding if overdosing or underdosing of either ingredient is occurring at any time. And success boils down to achieving sustainable and stable production of the target disinfectant, monochloramine.

  9. What Does The New Lead And Copper Rule Mean For Utilities?
    10/15/2019

    After nearly three decades since it was last modified, the U.S. EPA is set to update its Lead and Copper Rule — the primary regulation determining how much lead and copper is permissible in the public’s drinking water.

  10. WWEMA Window: WEFTEC 2019 From A Manufacturer Representative’s Perspective
    10/15/2019

    Many in our profession have recently returned from WEFTEC 2019, which was held in Chicago, IL, September 22 to 25, 2019. That week is one of the busiest weeks for manufacturer’s representatives, with the hosting of visiting clients to meet with various principals, principal training sessions, and time spent at the principals’ booths. WEFTEC gives us the opportunity to meet with key personnel from those principals who exhibit at WEFTEC (our firm had about 20 of our principals exhibiting) and to walk the exhibit floor to see if there are any new potential lines that we should secure. There is also a wealth of technical presentations for us to attend to keep abreast of the latest technology, regulatory, and government issues.
